We run clang in a docker container based on Ubuntu 16.04. In it we download
the tar.xz archive for clang, place it in /opt, and symlink it in using
`update-alternatives` (here's the line from our Dockerfile)
RUN export CLANG_VERSION=5.0.1 && \
export CLANG_PKG=clang+llvm-$CLANG_VERSION-x86_64-linux-gnu-ubuntu-16.04 &&

I'm finding that if I use any version after 5.0.1, clang exhibits a
segmentation fault with the `-g` option passed in. If I remove the
`-debug-info-kind=limited` command on the invocation below, the segmentation
fault does not happen. I believe this is a bug that needs to be fixed, but I'd
appreciate the insight of someone more knowledgable with clang. It seems to be
like more recent versions might be built without the option for ZLIB
compression enabled.
